CVE-2024-39818Network attack vector

Authenticated credential disclosure via undisclosed protection failure

Published Aug 14, 2024 · Updated Aug 16, 2024

Insufficient credential protection in Zoom Workplace Apps before 6.0.10 and VDI before 5.17.13 allows remote authenticated users to disclose data. Zoom has not published which credential storage or transmission locus lacks protection or how network input exposes the data. An authenticated Zoom context is required, and the documented consequence is disclosure only, without integrity or availability impact.
